I was hoping for an opinion on this list v. Grey Knights, because I've seen them slaughter prettymuch everything else I've thrown at them, tried maxing my powerklaws, they didn't even get to swing, tried giving everyone an invul-save so that they didn't get instantly insta-deathed. My next move is all shooty, and figured I'd try Flash Gitz to get around their armor saves using Orks.

I tried the list today and it did prettywell, but it was a tie against 'Nids.
